2016—2018年对海南三亚湾-红塘湾海岸开展了海陆联合地形监测。监测显示,三亚湾-红塘湾海岸存在海岸侵蚀。海岸地形演化过程与人类活动密切相关。三亚湾东部海岸由于人工补沙的影响,海岸地形处于重塑过程,季节上呈现冬淤夏蚀的特征,总体呈弱侵蚀。三亚湾西部由于开发活动,处于持续侵蚀状态。红塘湾海岸在近岸大规模填海前呈基本稳定的状态,填海之后出现明显的侵蚀现象。台风天气可造成严重的海岸侵蚀。台风天气造成的海岸侵蚀主要发生在海滩部分,对水下地形基本没有影响。
Abstract：According to the coastal topographic monitoring from 2016 to 2018 along the coastline of Sanya bay to Hongtang bay in Hainan island, there has coastal erosion that closely related to the human activities. Due to the influence of artificial sand supplement, the topography of eastern coast of Sanya Bay is reshaping, showing the characteristics of winter deposition and summer erosion in seasonal, which on the whole is weak erosion. The west of Sanya Bay is in a state of continuous erosion due to tourism development and urban construction. The coast of Hongtang Bay was basically stable before nearshore reclamation, and afterwards there is obvious erosion occurence. Typhoon weather can bring about serious coastal erosion that mainly occurs in the beach part, and has little effect on the underwater topography.
